Hey @PowerUser0 


I think out-of-box there is Facebook connector for Power Automate, but its designed to interface with timelines and posts and not leads.


Have a look at  - 


or you can use the HTTP action and invoke the API directly.


To be very honest, I have not explored the Facebook api much, but I hope links will point you the right direction

Hi @CFernandes ,


That custom connector does not work anymore now, its giving error , 

Hey @PowerUser0 


To be very honest, I am not much familiar with Facebook API.. The custom connector looked promising as it was backed up by a video tutorial..



Hi @CFernandes ,


Yeah I thought so too, but it seem @darogael has not updated it from long time, even many of the users have left comments there too,

but thanks for your help, I found a link too

A Microsoft Power Automate Custom Connector step-by-step from scratch: Facebook API | by András Förd... 

@fordosa90 can you help me on this?

Regular Visitor

@PowerUser0 I am bit under work currently but since you expressed that this is urgent, my first step recommendations would be to start with step-by-step, since there is no OOB connector currently to Facebook for your needs.

1. Simply interact first with the Facebook Graph API without any other tooling to understand the APIs you want to use: 

2. When ready, target the relevant Facebook APIs through Postman or similar (could be even your basic JS or C# code if you are more familiar with that). The aim is to be able to authenticate and successfully retrieve the data you are looking for. 

3. When ready, time to choose your actual Tooling. HTTP connector seems like a quick win, as you just use it the same way as what you did in step 2, however you loose a lot of control (eg DLP policies). Custom Connector can be the second option - especially if your organization is more mature - however that will come down the road with maintenance costs. Either way, you will only need to reuse how you have authenticated in Step 2 and to define the endpoint you are communicating with. 

Hi @fordosa90 ,


Thanks for the reply, but still I am not getting leads,

Now this is the spot, where your issue is not with PowerAutomate at the moment but rather understanding your target API. I strongly suggest using PostMan as a tool to get comfortable with the API you are trying to connect first, as described above, and only start to build your final flow with chosen tooling (PowerAutomate, C#, LogicApps, ...) when that second point is given.

Can you elaborate on error message you receive when trying to call the API?

Additional "quick checks" regarding your setup:
  - have you provided needed permissions to read Leads such as leads_retrieval? 

  - are you using default authentication or long-lived access tokens? In your screenshot I only see App Access Token (app id and secret) but documentation says you need at least a User Access Token to read leads. Those are usually valid up to 60 minutes, but you can convert them to Long Lived Tokens to extend the time window 

  - please realign your parameters as in the above screenshot you are trying to push your client ID and secret within the body of your request, instead of being header parameters .. Add the client_id, client_secret and grant_type (and all additional parameters) to the header and remove from the body

- use either the generic table of HTTP error codes to understand the issue you are facing or more specific Facebook API related ones: 

Hi @fordosa90  thanks a lot for your reply, I am able to get he leads using http action of power automate, but I  am getting page access token from Graph API Explorer tool of fb, there I gave permissions and clicked on generate token then I extended that token, but still sometime I get error in powerautomate  that your token is expired or you dnt have require access, 


but from 2 days I am not getting this error, not what I am trying to do is I am getting the leads from 2 forms of fb, this info is stored inside "field_data" array after parsing json, this goes inside apply to each loop, can you help me to create a common CSV table/excel where leads from all the forms gets stored ?refer screenshots of my full flow

1. I should pass permission from power automate http action to get the access token , I dnt want that everytime I should visit graph api explorer to get the tokens,

2. How I can create one CSV Table where leads from all the form are stored.


Let me know if some point is not clear
